Interesting story about this little 'shelf.' When I was looking at this house, the lady running the Open House mentioned that if I purchased a few barstools, this ledge would make a super spot for having breakfast in the mornings. It took a bit of restraint, but I managed to hold back a snort of laughter.
I'm assuming that the original intent for this was to rest plants. Either way, before we removed it, I had to try and see if it would have worked.
